A redesigned website can look completely finished and still be broken behind the scenes. Missing redirects, disconnected analytics, and untested forms don’t show up in a design review, they show up after launch, usually as a traffic drop or a lead that never reaches anyone. Here’s the checklist to run before that happens.

Quick Website Redesign Checklist
A successful launch takes more than checking whether the pages look good. Use this as a quick reference, then work through the full detail below for each item.
- 1. Test every page and link
- 2. Check mobile responsiveness
- 3. Review SEO elements
- 4. Set up redirects
- 5. Test forms and conversion paths
- 6. Check website speed and performance
- 7. Verify analytics and tracking
- 8. Review content and accessibility
- 9. Complete a final pre-launch QA check
The 9 Things to Check Before Launch
Test Every Page, Link, and Navigation Element
Broken links or missing pages damage both user experience and search visibility the moment real visitors arrive. Check main navigation, dropdown menus, internal and external links, buttons, calls to action, search functionality, footer links, forms, download links, embedded content, and 404 pages.
Test complete user journeys end to end, not just individual pages. For example: Homepage to Service Page to Contact Page to Form Submission to Confirmation. Following the full path catches breakages that page-by-page testing misses.
Check Mobile Responsiveness
The redesigned site needs to work across screen sizes, not just look fine when you shrink a desktop browser window. Check navigation, text size, buttons, forms, images, tables, spacing, pop-ups, sticky elements, and horizontal scrolling.
Test on actual devices where possible. Browser resizing tools are a useful first pass, but they miss real touch-target sizing issues and rendering quirks that only show up on an actual phone or tablet.
Review SEO Before Launch
Redesigns can unintentionally damage search visibility that took years to build, and SEO should be considered before launch, not patched in afterward. Check page titles, meta descriptions, heading structure, URLs, canonical tags, indexability, robots.txt, the XML sitemap, internal linking, and image alt text.
Identify which existing pages already perform well and preserve their value unless there’s a real strategic reason to change them. Following Google’s own Search Essentials guidance during a redesign is one of the more reliable ways to avoid accidentally breaking what already works. Our technical SEO breakdown covers the crawlability and indexing side of this in more depth.
Set Up and Test 301 Redirects
This is one of the most important technical steps in any redesign involving URL changes. Build a redirect map before launch: old URL to new URL, covering every deleted or renamed page. Google’s own documentation on redirects confirms that 301s tell search engines a page has permanently moved, and its site migration guidance specifically recommends keeping redirect chains short, ideally under three hops.
Redirects should point to the most relevant replacement page, not just the homepage. Redirecting every deleted URL to your homepage as a shortcut tells search engines (and visitors) that nothing on the old page actually matched anything on the new site.
Test Forms and Conversion Paths
A beautiful website isn’t successful if customers can’t actually contact the business. Test contact forms, quote requests, newsletter signups, demo requests, checkout flows, and account creation from both desktop and mobile.
Confirm submissions actually reach the right destination: the correct inbox, CRM, or sales team, not a dead address nobody checks. Where relevant, verify that form completions trigger the correct conversion tracking and advertising events. A form that silently fails is one of the costliest launch bugs, since nobody notices until a customer complains that they never heard back.
Check Website Speed and Performance
Performance affects both user experience and business outcomes. Review page loading, image sizes and formats, JavaScript and CSS, fonts, third-party scripts, caching, and lazy loading. Test high-value pages specifically, homepage, service pages, product pages, and contact pages, rather than only checking the homepage and assuming the rest follows.
PageSpeed Insights reports on Core Web Vitals, the performance signals covering loading, interactivity, and visual stability that Google documents in detail on web.dev.
Verify Analytics and Tracking
A redesign can accidentally remove or break tracking entirely, sometimes for weeks before anyone notices the data gap. Check Google Analytics, Google Tag Manager, Google Search Console, advertising pixels, conversion and event tracking, ecommerce or call tracking where applicable, and CRM integrations.
Test tracking both before launch on staging and immediately after going live. The exact setup depends on your specific tech stack and privacy requirements, but the principle is universal: verify it works before you need the data, not after.
Review Content and Accessibility
Content: check spelling and grammar, outdated information, contact details, hours, pricing, service descriptions, testimonials, and legal information. Make sure everything is accurate and consistent across the whole site, not just the pages the redesign team focused on most.
Accessibility: check color contrast, descriptive link text, alt text on meaningful images, keyboard navigation, form labels, heading hierarchy, and video captions where applicable. The W3C’s Web Content Accessibility Guidelines are the standard reference here. A checklist pass is a good baseline, but it doesn’t guarantee legal accessibility compliance, professional accessibility testing is worth it for sites with real legal exposure.
Complete a Final Pre-Launch QA Check
Bring everything together: desktop, mobile, multiple browsers, forms, navigation, links, SEO, redirects, analytics, performance, accessibility, content, and integrations. Have someone who wasn’t heavily involved in the redesign do this final pass. Fresh eyes catch things the project team has stopped noticing after weeks of staring at the same pages.

What to Do Immediately After Launch
The checklist doesn’t end when the site goes live. Keep a close watch during the first days and weeks: Search Console, analytics, traffic patterns, rankings, conversions, form submissions, 404 errors, redirect behavior, page performance, and how tracking is actually behaving with real traffic.
Not every traffic fluctuation after a redesign means something broke. Some short-term movement is normal while search engines reprocess the new site. What’s worth investigating is a sustained drop, a spike in 404s, or a conversion path that’s clearly not registering completions anymore.
Common Website Redesign Mistakes
- ✕ Launching without a redirect map. Build it before launch, not after traffic starts dropping.
- ✕ Changing URLs unnecessarily. Every URL change is a redirect that has to work perfectly. Don’t create the risk without a reason.
- ✕ Forgetting analytics. Verify tracking on staging before launch, not after you notice a data gap.
- ✕ Testing only the homepage. Test the pages that actually drive business, service pages, contact pages, and landing pages.
- ✕ Ignoring mobile. Most traffic is mobile for most businesses. Test on real devices.
- ✕ Removing valuable content. Check what’s actually ranking or converting before cutting a page during redesign.
- ✕ Failing to test forms. A form that silently fails can go unnoticed for weeks.
- ✕ Launching without SEO checks. Fix this before launch, recovering lost rankings afterward takes far longer.
- ✕ Assuming staging behaves like production. Server configs, caching, and redirects often differ between environments.
- ✕ Not monitoring after launch. The first few weeks are when problems are cheapest to catch and fix.
Frequently Asked Questions
What should I check before launching a redesigned website?
Test every page and link, check mobile responsiveness, review SEO elements, set up redirects, test forms, check speed and performance, verify analytics, review content and accessibility, and complete a final QA pass before going live.
How do I protect SEO during a website redesign?
Build a full redirect map before launch, preserve titles and content on pages that already perform well, keep your XML sitemap and robots.txt correct, and verify indexability before and after launch rather than assuming everything carried over.
What SEO checks should I complete before a website launch?
Check page titles, meta descriptions, heading structure, URLs, canonical tags, indexability, robots.txt, the XML sitemap, internal linking, and image alt text, then confirm 301 redirects are set up for any URLs that changed.
What should I do immediately after launching a redesigned website?
Monitor Search Console, analytics, traffic, rankings, conversions, form submissions, and 404 errors closely for the first several weeks. Some short-term fluctuation is normal, but sustained drops or broken tracking are worth investigating immediately.
Does completing this checklist guarantee a successful launch?
No checklist can guarantee outcomes like traffic, rankings, or conversion rates. What it can do is catch the avoidable technical and content issues that commonly cause problems after a redesign, which puts the site in the best realistic position to perform well.
Before You Hit Publish
A redesign that looks finished isn’t the same as a redesign that’s ready. The gap between the two is almost always in the parts nobody sees on a screenshot: redirects, tracking, form delivery, and technical SEO. Work through these nine checks before launch, and the biggest post-launch surprises become far less likely.
